can't delete UIWebView - ios

Question

I create UIScrollView and inside it I create multiple UIWebViews to scroll between them.
For memory management I give each UIWebView a tag when it created and after I scroll to the next I remove it with the tag but I still have memory issue and application quit.
Can any one have a better idea about delete the unused UIWebView delete the after next+1 & previous-1
this is my code
note {i use ARC}
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView {
// NSLog(#"will ViewDidEndDecelerating ");
// NSLog(#"HI I AM end decelerating ");
if (lastContentOffset < (int)self.scrollView.contentOffset.x) {
if (pageReference < 5) {
pageReference ++;
if (pageReference>1) {
[[self.scrollView viewWithTag:pageReference-1] removeFromSuperview];
// UIWebView*deleted =[[UIWebView alloc]init];
// NSLog(#"delete page number%d ",pageReference-1);
}else{//NSLog(#"exep error");
}
}
if (pageReference>3) {
// NSLog(#">>>>>>>>>4 %d",pageReference);
}else{
[self createWebViewWithTag:pageReference+1];
}
// NSLog(#"iam at te end of deckleration ++ and my page reference is %d",pageReference);
// [[self.scrollView viewWithTag:tag-3] removeFromSuperview];
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:pageReference inSection:0];
[self.tableView deselectRowAtIndexPath:indexPath animated:YES];
[self.tableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:(0)];
// NSLog(#"page : %d",pageReference);
// [self setupScrollView];
// startTime = mach_absolute_time();
// [self saveData];
}
else if (lastContentOffset > (int)self.scrollView.contentOffset.x) {
// NSLog(#" Move back");
if (pageReference>0) {
pageReference --;
// NSLog(#"iam at te end of deckleration -- and my page reference is %d",pageReference);
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:pageReference inSection:0];
[self.tableView deselectRowAtIndexPath:indexPath animated:YES];
[self.tableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:(0)];
// NSLog(#"page : %d",pageReference);
if (pageReference>0) {
// NSLog(#"Create Reference %d",pageReference);
[self createWebViewWithTag:pageReference-1];
}
else{
// NSLog(#"iam not need -1 view ");
}
// startTime = mach_absolute_time();
// [self saveData];
}
else {
// NSLog(#"no Move ");
}
// NSLog(#"page Reference : %d",pageReference);
}else{
//NSLog(#"restricted < 0 ");
}
}
- (void) createNextWebViewWithTag:(int)tag {
// NSLog(#"The Current WebViewTagIn NextView Creation%d",tag);
int tagPlusOne= tag+1 ;
// int tagMinusOne= tag-3 ;
int DimensionXpoint = tagPlusOne*1024;
UIWebView*webview = [[UIWebView alloc] initWithFrame:CGRectMake(DimensionXpoint , 0, 1024, 768)];
webview.tag = tagPlusOne;
// NSLog(#"webView THe Tag%d",webview.tag);
webview.delegate = self;
webview.scrollView.delegate = self;
webview.scrollView.scrollEnabled = NO;
// currentSlide= [NSString stringWithFormat:#"procto_slide%d", tagPlusOne];
// currentSlideReference = [NSString stringWithFormat:#"HemaGel_procto_0%d", tagPlusOne];
// NSString *Currentpath = [[NSBundle mainBundle] pathForResource:currentSlide ofType:#"html"inDirectory:currentSlideReference];
//////////////
// NSURL *currentUrl = [NSURL fileURLWithPath:Currentpath];
// NSURLRequest *Currentrequest = [NSURLRequest requestWithURL:currentUrl];
[webview loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:#"Slide_%d", tagPlusOne] ofType:#"html"inDirectory:[NSString stringWithFormat:#"Slide_%d", tagPlusOne]]]]];
[self.scrollView addSubview:webview];
// UIWebView *deleted = [[UIWebView alloc]init];
/* if (tag>3) {
[[self.scrollView viewWithTag:tag-3] removeFromSuperview];
NSLog(#"webView.Tag %d",webview.tag);
}*/
}
